They found that calcification rates (rate at which coral polyps secrete their limestone skeletons) increased 5.4 per cent between 1900 and 1970, but have dropped 14.2 per cent from 1990 to 2005, mainly due to a slowdown in growth from 1.43 centimetres per year to 1.24 centimetres per year.</DIV></blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/A0E3CACC-EE4D-43ED-8CE6-652E173681AF/blog/" title="blog or email this clip"><img src="http://content8.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
